The aviation sector has been significantly impacted due to the travel restrictions imposed in India and other countries amid the coronavirus pandemic.
State-run Air India has shuttered five of its stations in Europe amid the COVID-19 pandemic-led economic disruption. The national carrier has closed the offices in Vienna, Milan, Madrid, Copenhagen and Stockholm, news agency ANI has reported.
"In view of #COVID19, Air India (AI) has decided to close down its stations in Vienna, Milan, Madrid, Copenhagen, & Stockholm. AI would immediately initiate action for closure in consultation with local lawyers & advise the timelines by which the stations will be closed," news agency ANI had tweeted.
Last month, Air India began the process of identifying staff, based on various factors, who will be sent on compulsory leave without pay. It also withdrew job offers for around 180 trainee cabin crew members. The decisions have been taken as part of the airlines' cost-cutting measures amid the economic slowdown in the Indian aviation sector due to the coronavirus pandemic.

Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
